Abstract

A találmány tárgya légrugó kettős gördülő huzattal. A légrugó (2) két,koaxiálisan egymással szemben elrendezett rugóelemet (4a, 4b)tartalmaz. Ezek a rugóelemek lényegében egy-egy gördülő huzatból (6a,6b) és egy-egy legördítő dugattyúból (8a, 8b) állnak. A két gördülőhuzat (6a, 6b) közös kettős gördülő huzatot (6) képez, és a kétrugóelemnek (4a, 4b) közös külső köpenye (10) van. A találmányértelmében a kettős gördülő huzat (6) el van látva egy belülelhelyezett támaszgyűrűvel (14), amely a kerületi oldalon radiálismélyedéssel (16) van ellátva, és a külső palást (10) belső kerületénkörben van egy kiemelkedés, amelybe a támaszgyűrű (14) kerületioldalon lévő radiális mélyedése (16) benyúlik és így szorító kontúrtképez. A támaszgyűrűben (14) lehet egy további szorítási hely (a 16aés 16b mélyedés). ÓThe subject of the invention is an air spring with a double rolling cover. The air spring (2) contains two coaxially opposite spring elements (4a, 4b). These spring elements essentially consist of a rolling cover (6a, 6b) and a roll-down piston (8a, 8b). The two rolling covers (6a, 6b) form a common double rolling cover (6), and the two spring elements (4a, 4b) have a common outer jacket (10). According to the invention, the double rolling cover (6) is equipped with an internally placed support ring (14), which is equipped with a radial recess (16) on the peripheral side, and there is a projection around the inner circumference of the outer shell (10) into which the support ring (14) is inserted on the peripheral side its radial recess (16) extends and thus forms a clamping contour. In the support ring (14) there can be an additional clamping place (recesses 16a and 16b). HE
